The Traxxas X-Maxx® is a giant that forever changed the face of RC monster trucks. Its radical cutting-edge design, massive size, brutal strength, and unmatched power transformed X-Maxx into the stuff of legends. The 1/10 Traxxas Maxx® expertly packages X-Maxx’s innovative design elements and jaw-dropping strength into a lighter, more compact, even more ferocious beast. Now the newest Maxx is even bigger, with a longer wheelbase, beefier Sledgehammer® tires, and that incredible WideMaxx® stance for even more intense action. Let the fun begin!

WideMaxx stance stretches the wheels out over 1.5 inches (40 mm) wider for even greater stability.

The extended chassis length now accommodates our most powerful batteries, the same 6700mAh 4-cell LiPo batteries used in the X-Maxx.

Taller Sledgehammer tires feature an aggressive open-block tread design that clears away mud and debris for unrivaled traction.
